Those readers who have found post–cold war le Carré too cerebral will have much to cheer about with this Russian mafia spy thriller. While on holiday in Antigua, former Oxford tutor Perry Makepiece and his lawyer girlfriend, Gail Perkins, meet Dmitri "Dima" Vladimirovich Krasnov, an avuncular Russian businessman who challenges Perry to a tennis match. Even though Perry wins, Dima takes a shine to the couple, and soon they're visiting with his extended family. At Dima's request, Perry conveys a message to MI6 in England that Dima wishes to defect, and on arriving home, Perry and Gail receive a summons from MI6 to a debriefing. Not only is Dima a Russian oligarch, he's also one of the world's biggest money launderers. Le Carré ratchets up the tension step-by-step until the sad, inevitable end. His most accessible work in years, this novel shows once again why his name is the one to which all others in the field are compared. (Oct.)
